DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

Reference will now be made in detail to the present preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numerals will be used throughout the drawings to refer to the same or like parts.

For purposes of description herein, the terms “upper,” “lower,” “right,” “left,” “rear,” “front,” “vertical,” “horizontal,” “top,” “bottom,” and derivatives thereof shall relate to the invention as viewed in FIG. 1. However, it is to be understood that the invention may assume various alternative orientations, except where expressly specified to the contrary. It is also to be understood that the specific device illustrated in the attached drawings and described in the following specification is simply an exemplary embodiment of the inventive concepts defined in the appended claims. Hence, specific dimensions, proportions, and other physical characteristics relating to the embodiment disclosed herein are not to be considered as limiting, unless the claims expressly state otherwise.

The reference number 10 (FIG. 1) generally designates a rearview mirror assembly for a vehicle embodying the present invention. In the illustrated example, the rearview mirror assembly 10 comprises a housing 12 including a rear housing section 34 and a bezel 36, and a mounting bracket 29 connecting the housing 12 to a vehicle. The housing includes a circuit board 38, a carrier plate 32 and a reflective element 16 therein. The rear housing section 34 includes wiring 50 connected to a first electrical connection device 52. The circuit board 38 includes a second electrical connection device 54. The first electrical connection device 52 and the second electrical connection device 54 are configured to automatically mate when the circuit board 38 and the rear housing section 34 are moved relatively towards each other.

The illustrated rearview mirror assembly 10 of the present invention can be used in an interior rearview mirror. When the rearview mirror assembly 10 is used in an interior rearview mirror, the rearview mirror assembly 10 is preferably connected to the mounting bracket 29, which is adapted to be mounted inside the vehicle in a location proximate to or on a front windshield of the vehicle. The interior rearview mirror can have a single ball mount or a double ball mount 40 (see FIGS. 1 and 3-5). An example of a rearview mirror assembly connected to a mounting bracket having a single ball mount is disclosed in U.S. Pat. No. 6,467,919 entitled MIRROR WITH SPLIT BALL MOUNT AND HOLD-OPEN DEVICE, the entire contents of which are hereby incorporated herein by reference. An example of a rearview mirror assembly connected to a mounting bracket having a double ball mount is disclosed in U.S. Patent Application Publication No. 2005/0174663 entitled REARVIEW MIRROR WITH INTEGRATED FRAME, the entire contents of which are hereby incorporated herein by reference. The mounting bracket 29 is connected to the windshield as discussed above and/or a headliner of the vehicle as is well know to those skilled in the art and as disclosed in U.S. Pat. Nos. 6,467,919 and 5,377,948.

In the illustrated example, the housing 12 of the rearview mirror assembly 10 includes the carrier plate 32 located behind the reflective element 16. The carrier plate 32 can include the circuit board 38 connected thereto. If the rearview mirror assembly 10 is used in an interior rearview mirror, the carrier plate 32 is typically fixed in position within the housing 12. The carrier plate 32 of the interior rearview mirror can be used to maintain the position of the reflective element 16 and/or carry the circuit board 38. An example of an interior review mirror including a carrier plate and a circuit board is disclosed in U.S. Pat. No. 6,239,899, entitled MIRROR WITH INTERNAL SUPPORT PLATE, the entire contents of which are hereby incorporated herein by reference. In the interior rearview mirror, the carrier plate 32 assists in maintaining the reflective element 16 in position within the housing 12. The rear housing section 34, bezel 36, carrier plate 32, circuit board 38 and their interconnections are well known to those skilled in the art (except for any alterations discussed herein). An example of a rear housing section, a bezel, a carrier plate, a printed circuit board and their interconnections with a mount is disclosed in U.S. Patent Application Publication No. 2005/0152054 entitled REFLECTIVE ELEMENT HOLDER FOR REARVIEW MIRROR, the entire contents of which are hereby incorporated herein by reference.

In the illustrated example, the circuit board 38 and the reflective element 16 are located adjacent the carrier plate 32. The carrier plate 32 includes a first face 42 and a second face 44. The circuit board 38 is located adjacent the second face 44 of the carrier plate 32. The circuit board 38 includes a first side 46 facing the carrier plate 32 and a second side 48 facing away from the carrier plate 32. The reflective element 16 is located adjacent the first face 42 of the carrier plate 32.

The illustrated reflective element 16 of the present invention can comprise an electrochromic (EC) mirror subassembly having a front glass element 100 and a rear glass element 102. The illustrated front glass element 100 and the rear glass element 102 are preferably less than 2.2 mm, or more preferably less than about 1.6 mm down to about 1.1 mm. A more detailed description of reflective elements 16 having glass elements of a thickness of 1.1 mm is disclosed in U.S. Pat. No. 6,195,194 entitled LIGHTWEIGHT ELECTROCHROMIC MIRROR, the entire contents of which are hereby incorporated herein by reference. In the illustrated embodiment, the reflective element 16 is in an interior rearview mirror and therefore has a reflectance value of about 70 percent or greater.

The illustrated reflective element 16 includes an electrochromic (EC) material positioned between the front glass element 100 and the rear glass element 102. Furthermore, a reflector material is preferably located on either the front surface or the rear surface of the rear glass element 102, depending upon the type of the mirror subassembly. The EC material is preferably a solution phase (sometimes called herein a “liquid-phase” or “gel-type”) EC material, as disclosed in U.S. Pat. No. 4,902,108 entitled SINGLE-COMPARTMENT, SELF-ERASING, SOLUTION-PHASE ELECTROCHROMIC DEVICES, SOLUTIONS FOR USE THEREIN, AND USES THEREOF and U.S. Pat. No. 5,278,693 entitled TINTED SOLUTION-PHASE ELECTROCHROMIC MIRRORS, the entire contents of both of which are hereby incorporated herein by reference. In addition, a hybrid system where part of the electrochromic medium is solid-state and part is solution phase is also contemplated. Solution-phase materials, because of their liquidic or flowable properties, do not rigidly bond the front glass element 100 and the rear glass element 102 together like a completely solid-state EC medium. As a result, the stiffness of the reflective element 16 using 1.1 mm thick glass elements and a solution-phase EC material is more flexible than an EC mirror subassembly having 1.1 mm thick glass elements and a solid-state phase EC material because, in the reflective element 16 having solid-state phase EC material, the thick glass elements are bonded together in a manner that causes them to bend much like a single glass element having their total thickness. Contrastingly, the reflective element 16 with the solution phase EC material bends in a complex manner wherein the thin glass elements bend simultaneously but independently and separately and wherein the solution phase EC material ebbs and flows somewhat in reaction to the stress. The net result is that the mirror subassembly with solution phase EC material tends to be more flexible and concurrently more sensitive to impact than the mirror subassembly with solid-state phase EC material, even where the front and rear glass elements have the same thickness and other properties. Although the reflective element 16 is illustrated as including the EC material, it is contemplated that the reflective element 16 could any type of reflective surface. For example, the reflective element 16 could be a prismatic mirror.

In the illustrated example, wiring 50 is routed through the mounting bracket 29 and into the housing 12 for supplying and/or receiving power and control to circuits on the circuit board 38. For example, the wiring 50 can be used to power the EC mirror as discussed above or power and/or control and of the electrical components discussed in more detail below. In the illustrated example, the wiring 50 enters the rear housing section 34 through the mounting bracket 29. However, it is contemplated that the wiring 50 could enter the rear housing section 34 through any portion of the rear housing section 34. In the illustrated embodiment, the mounting bracket 39 includes a ball section 56 connected to the rear housing section 34, with the ball section 56 including a center opening 58 having the wiring 50 routed therethrough (see FIG. 5). The ball section 56 includes a mounting plate 60 connected to an outside of a flat portion 62 of the rear housing section 34 by a plurality of screws 64. The plurality of screws 64 are also connected to a mounting washer 66 on an inside of the flat portion 62 of the rear housing section 34, thereby connecting the ball section 56 and the mounting bracket 29 to the housing 12. As illustrated in FIGS. 2 and 5, the wiring 50 extending through the ball section 56, through an opening in the flat portion 62 of the rear housing section 34, and through a center opening 68 in the mounting washer 66. The wiring 50 can comprise a plurality of wires 51 within an outer sheath (as shown) and/or at least one wire 51. As illustrated in FIGS. 2 and 6, the rear housing section 34 can include at least one clip 70 for retaining the wiring 50 in the rear housing section 34. The clips 70 can include a first clip 72 that extends from the flat portion 62 of the rear housing section 34 and through an opening 74 in the mounting washer 66. The clips 70 can also include a second clip 74 extending from an inside surface 76 of the rear housing section 34. The wiring 50 is connected to the first electrical connection device 52.

The illustrated first electrical connection device 52 (see FIGS. 9-12) is connected to the rear housing section 34 and is configured to be removably connected to the second electrical connection device 54. The first electrical connection device 52 can be any device for electrically connecting the wiring 50 to the second electrical connection device 54. In the illustrated embodiment, the first electrical connection device 52 comprises a connection block 78 having a first portion 80 for accepting the wiring 50 therein and a second portion 82 for electrical connection to the second electrical connection device 54. The first portion 80 includes a plurality of receptacles 84 for receiving individual wires of the wiring 50. The receptacles 84 can include any mechanism for securing the wires thereto and for supplying and/or receiving power and control to circuits. As illustrated in FIGS. 11 and 12, the receptacles 84 can each include at least one U-shaped knife connector 86. Therefore, the wires 51 can be connected to the first electrical connection device by inserting ends of the wires 51 through a bottom aperture 88, such that the wires 51 are captured by the U-shaped knife connector 86 in the receptacle 84. The U-shaped knife connector 86 allow the wires 51 to be inserted into the receptacles without removing the insulation from the wires 51 as the U-shaped knife connector 86 will cut through the insulation to make an electronic connection between the wires 51 and the U-shaped knife connector 86. Each receptacle 84 can also include a clip 90 for holding the wires 51 within the receptacle 84.

In the illustrated example, the first portion 80 of the connection block 78 also includes at least one slot 92 for connecting the first electrical connection device 52 to the rear housing section 24. In the illustrated example, the first portion 80 includes a first slot 93 located in line with the receptacles 84 and a second slot 94 perpendicular to the first slot 93. As illustrated in FIG. 6, the rear housing section 34 includes at least one peg 96 for insertion into the slots 92 to removably connect the first electrical connection device 52 to the rear housing section 34. It is contemplated that at least one of the pegs 96 could include a tab on a terminal end thereof to snap fit the first electrical connection device 52 to the rear housing section 34 in a stable manner. The first portion 80 can also include a third slot 98 (or more slots) for connection with further pegs 96 extending from the rear housing section 34. However, it is contemplated that the rear housing section 34 could only include one or two pegs 96 for engagement with one or two slots 92 to thereby allow various first electrical connection devices 52 having any number of receptacles 84 to be connected thereto (i.e., since only one or two sides of the first portion 80 with slots are connected to the rear housing section, the first portion 80 can be of any length to accommodate any number of receptacles 84). It is further contemplated that the first portion 80, and thereby the first electrical connection device 52 could be fixedly connected to the rear housing section 34 or removably connected to the rear housing section 34 in any manner (e.g., heat staking, screwing, welding, etc.).

The illustrated second portion 82 of the first electrical connection device 52 is configured to be connected to the second electrical connection device 54. The second portion 82 includes a plurality of openings 110 facing towards the second side 48 of the circuit board 38. Each openings 110 has an electrical connector therein connected to one of the U-shaped knife connectors 86 in the receptacles 84 to allow items being inserted into the openings 110 to be electrically connected to the U-shaped knife connectors 86 in the receptacles 84 and thereby the wires 51.

In the illustrated embodiment, the second electrical connection device 54 (see FIGS. 8 and 13-15) is connected to the second side 48 of the circuit board 38 and is configured to be connected to the first electrical connection device 52. The second electrical connection device 54 includes a base 112 connected to the circuit board 38. A plurality of prongs 114 extend through the base 112 and into the circuit board 38. The prongs 114 are electrically connected to circuits on the circuit board 38. As illustrated in FIGS. 8, 14 and 15, the base 112 includes a receiving slot 116 facing away from the second side 48 of the circuit board 38. The prongs 114 extend into the receiving slot 116. The base 112 also includes at least one funnel extension 118 surrounding the receiving slot 116. The funnel extension 118 includes at least one funnel surface 120 slanted towards the receiving slot 116. In the illustrated embodiment, the base 112 includes a pair of funnel extensions 118. However, it is contemplated that the base 112 could include any number of funnel extensions 118 (including only one).

The illustrated first electrical connection device 54 is configured to be connected to the first electrical connection device 52 by inserting the second portion 82 of the first electrical connection device 52 into the receiving slot 116 in the base 112 of the second electrical connection device 54. The funnel extensions 118 assist in funneling the second portion 82 of the first electrical connection device 52 into the receiving slot 116 in the base 112 of the second electrical connection device 54 by having the second portion 82 of the first electrical connection device 52 ride along at least one of the funnel surfaces 120 of at least one funnel extension 118. Once the second portion 82 of the first electrical connection device 52 is fully inserted into the receiving slot 116 in the base 112 of the second electrical connection device 54, the prongs 114 will extend into the openings 110 to thereby create at least one circuit between the wires 51 and the circuit board 38.

In the illustrated example, the second portion 82 of the first electrical connection device 52 will automatically be received within the receiving slot 116 in the base 112 of the second electrical connection device 54 as the circuit board 38 is moved towards the rear housing section 34. As illustrated in FIGS. 2, 6 and 7, the inside surface 76 of the rear housing section 34 includes a plurality of guide posts 130 extending therefrom. The guide posts 130 include ledges 132 for accepting the circuit board 38 thereon. The inside surface 76 of the rear housing section 34 includes a number of the guide posts 130 to allow the circuit board 38 to be correctly positioned relative to the rear housing section 34. Therefore, as the circuit board 38 is moved relatively towards the rear housing section 34, the guide posts 130 will move the circuit board 38 into position within the rear housing section 34 and simultaneously position the receiving slot 116 in the base 112 of the second electrical connection device 54 such that is will automatically receive the second portion 82 of the first electrical connection device 52. Consequently, the rearview mirror assembly 10 can be constructed by routing the wiring 50 through the rear housing section 34, connecting the wiring 50 to the first electrical connection device 52, positioning the first electrical connection device 52 within the rear housing section 34, moving the circuit board 38 (and optionally the carrier plate 32 and the reflective element 18 at the same time) relatively towards the rear housing section 34 as discussed directly above, and connecting the bezel 36 to the rear housing section 34.

As illustrated in FIG. 16, it is further contemplated that the circuit board 38 and the reflective element 16 could have an electrically connection assembly 200 a for automatically mating a third electrical connection device 300 on the circuit board 38 with a fourth electrical connection device 304 on the reflective element 16 when the circuit board 38 and the reflective element 16 are moved relative towards each other as discussed above, thereby providing power to the EC material in the reflective element 16 (if the reflective element 16 includes EC material). Providing power to EC material and the results thereof are described above. Therefore, the rearview mirror assembly 10 can have an electrical connection from the wiring 50, through the first electrical connection device 52, through the second electrical connection device 54, through the circuit board 38, through the third electrical connection device 300 and to the fourth electrical connection device 304 and to the EC material in the reflective element 16. It is noted that although only one third electrical connection device 300 and one fourth electrical connection device 304 are illustrated in FIG. 16, typically two third electrical connection devices 300 and two fourth electrical connection devices 304 would be used. However, it is contemplated that only one or more than two third electrical connection devices 300 and fourth electrical connection devices 304 could be used.

FIGS. 16 and 18 illustrate a first embodiment of the third electrical connection device 300. The third electrical connection device 300 can comprise a compressible conductive pad mounted on the circuit board 38. For example, the compressible conductive pad could comprise a gasket and grounding pad comprised of a conductive silver-coated hollow silicone extrusion bonded to a solderable silver-plated metal support layer such as that sold under the trademark Gore-Shield® by W.L. Gore & Associates, Inc. of Newark, Del. and as disclosed in U.S. Pat. Nos. 6,255,581 B1 and 7,129,421 B2, the entire contents of both of which are hereby incorporated herein by reference. The compressible conductive pad can include a solder member 305 for connecting the compressible conductive pad to the circuit board 38. In the illustrated example, as the circuit board 38 is moved towards the reflective element 16, the third electrical connection device 300 will automatically mate with the fourth electrical connection device 304.

In the illustrated example, a first embodiment of the fourth electrical connection device 304 (FIGS. 16 and 17) comprises a bus clip 306 and a connection clip 307 that connects to the reflective element 16. The connection clip 307 includes a first section 308 configured to clip over an edge of the reflective element 16 (and connect with the bus). The connection clip 307 also includes a second section 312 comprising a plate resiliently connected to the first section 308 via a spring plate 310. The spring plate 310 forces the second section 312 outward and away from the reflective element 16.

As illustrated in FIG. 16, as the reflective element 16 is moved along line 320 and the circuit board 38 is moved along line 322 (or only the reflective element 16 is moved along line 320 or only the circuit board 38 is moved along line 322), the third electrical connection device 300 will automatically mate with the fourth electrical connection device 304 by having the second section 312 of the connection clip 307 of the fourth electrical connection device 304 abut an outside surface of the compressible conductive pad of the third electrical connection device 300. It is contemplated that the second section 312 of the connection clip 307 of the fourth electrical connection device 304 can include a conductive finish to assist in the connection. It is further contemplated that the connection clip 307 may be entirely omitted, such that the fourth electrical connection device 304 comprises the bus clip 306.

FIGS. 19-21 illustrate a second embodiment of the electrically connection assembly 200 b for automatically mating a second embodiment of the third electrical connection device 400 on the circuit board 38 with a second embodiment of the fourth electrical connection device 405 on the reflective element 16 when the circuit board 38 and the reflective element 16 are moved relative towards each other as discussed above, thereby providing power to the EC material in the reflective element 16 (if the reflective element 16 includes EC material). Providing power to EC material and the results thereof are described above. Therefore, the rearview mirror assembly 10 can have an electrical connection from the wiring 50, through the first electrical connection device 52, through the second electrical connection device 54, through the circuit board 38, through the third electrical connection device 400 and to the fourth electrical connection device 405 and to the EC material in the reflective element 16. It is noted that although only one third electrical connection device 400 and one fourth electrical connection device 405 are illustrated in FIG. 19, typically two third electrical connection devices 400 and two fourth electrical connection devices 405 would be used. However, it is contemplated that only one or more than two third electrical connection devices 400 and fourth electrical connection devices 405 could be used.

FIGS. 19-22 illustrate a second embodiment of the third electrical connection device 400. The third electrical connection device 400 can comprise an L-shaped conductor having a first portion 404 connected to the circuit board 38 and a second portion 402 configured to engage a second embodiment of the fourth electrical connection device 405. The second embodiment of the fourth electrical connection device 405 can comprise a first section 416 configured to clip over an edge of the reflective element 16 (and connect with the bus), a second section 408 substantially perpendicular to the first section 416 (and substantially aligned with a rear face of the reflective element 16) and a third section 410 substantially perpendicular to the second section 408. The third section 410 of the second embodiment of the fourth electrical connection device 405 includes a plurality of first downwardly angled fingers 412 and a plurality of second upwardly angled fingers 414.

As illustrated in FIGS. 19-22, as the reflective element 16 is moved along line 420 and the circuit board 38 is moved along line 422 (or only the reflective element 16 is moved along line 420 or only the circuit board 38 is moved along line 422), the second embodiment of third electrical connection device 400 will automatically mate with the second embodiment of the fourth electrical connection device 405 by having the second portion 402 of the L-shaped conductor of the second embodiment of third electrical connection device 400 mate with the third section 410 of the second embodiment of the fourth electrical connection device 405. The second portion 402 of the L-shaped conductor of the second embodiment of third electrical connection device 400 mates with the third section 410 of the second embodiment of the fourth electrical connection device 405 by inserting the second portion 402 between the plurality of first downwardly angled fingers 412 and the plurality of second upwardly angled fingers 414 as illustrated in FIG. 22. It is contemplated that the second embodiment of third electrical connection device 400 and the second embodiment of the fourth electrical connection device 405 can include conductive finishes to assist in the connection.

It is noted that the first and second embodiments of the third electrical connection device and the fourth electrical connection device described above are believed to provide a low impedance DC and RF electrical connection between the circuit board 38 and the reflective element 16 that prevents the reflective element 16 from becoming a passive antenna.

It is contemplated that the present inventive concepts can be used in combination with mirrors (interior and/or exterior) having many different options to create synergistic and non-obvious combinations that provide surprising and unexpected benefits not previously possible. Therefore, it will be appreciated by those skilled in the art that various other vehicle accessories and components may be incorporated in the previously described rearview mirror assembly 10 for a vehicle in whole or in part and in various combinations. Such vehicle accessories and components may be mounted within, on or to the housing 12, the mounting bracket 29, attachment to the mirror housing 12 or the mounting bracket 29, or in a console or other housing associated with the interior rearview mirror having the rearview mirror assembly 10 of the present invention. Additionally, any such vehicle accessories may share components with one another, such as processors, sensors, power supplies, wire harnesses and plugs, displays, switches, antennae, etc. Examples of other vehicle accessories, components or features are described further below.

An example of a system incorporated in the interior rearview mirror includes an electronic compass system within the housing 12 of the interior rearview mirror as described in U.S. Pat. No. 7,149,627 entitled ELECTRONIC COMPASS SYSTEM, the entire contents of which are incorporated in its entirety herein by reference. FIGS. 22A-22C show another embodiment of the interior rearview mirror in which any of the electronic compass systems described in U.S. Pat. No. 7,149,627 are incorporated. As illustrated in FIGS. 23A-23C, the housing 12 comprises the bezel 36 and the rear housing section 34. The bezel 36 and the rear housing section 34 combine to define the housing 12 for incorporation of features in addition to a reflective element 16 and information displays 905 a and 905 b. Commonly assigned U.S. Pat. Nos. 6,102,546, D410,607, 6,407,468, 6,420,800, and 6,471,362, the disclosures of which are incorporated in their entireties herein by reference, describe examples of various bezels, cases and associated button constructions that may be used with the present invention.
